So Mike, when are you gonna give up and re-forge a standard cross pein hammer head round??
Seems like all you'd have to do is anchor a couple of iron blocks on the anvil and lay the hot head across it,
then wallop a handled swage (need a second guy here) with a sledge, to bend the head round. Probably take a couple/3 heats.
Then of course the eye would have to be drifted back out,
after the assault heehe...
It might be a little short compared to the old ones, but it'd do the job.
Need to borrow a large, handled, top swage?
Or just show up at my door. It'd take some time but we'd figure something out. ;)
yours Scott
